2008-09-12 Christian Neumair <cneumair@gnome.org> * libnautilus-private/nautilus-icon-canvas-item.c (nautilus_icon_canvas_item_set_is_visible), (nautilus_icon_canvas_item_invalidate_label): * libnautilus-private/nautilus-icon-canvas-item.h: * libnautilus-private/nautilus-icon-container.c (invalidate_labels), (nautilus_icon_container_set_layout_mode), (nautilus_icon_container_set_label_position), (nautilus_icon_container_set_font), (nautilus_icon_container_set_font_size_table), (nautilus_icon_container_set_all_columns_same_width): Add nautilus_icon_canvas_item_invalidate_label(), which removes the associated PangoLayout - used when resetting attributes, e.g. when the zoom level changes or when switching from “text below” to “text besides” mode. Fixes #551862. svn path=/trunk/; revision=14616
